I purchased a TB47 Battery in March 2015, bringing to 5 the number of batteries I had for my I1. I have used a combination of a Smart Powercharge unit and a light discharge system to carefully follow the rules for looking after LiPo's. I usually rotated through the 5 batteries so I believe it had been used for about 20 flights. Last week when I went to discharge the battery using the light system it "bricked". I tried a number of ways to fix it (put it in the I1 with the latest .bin file, tried multiple ways to charge it, and eventually, accepting that I was unlikely to get any joy from the interstate source of my battery - I popped the top and disconnected the small plug). All to no avail. I believe the battery is about 95% charged and my question is how can I dispose of it safely. I do not think I want to take any more drastic measures to get it un-bricked, as I'm not sure I will trust it again. I think I'd rather buy a new battery rather than risk a mid-flight battery failure. Many thanks in anticipation.
